For decades, astronomers have cast galaxy mergers as the universe's ultimate relationship drama: two galaxies collide, chaos ...

Most galaxy collisions do not cause galaxies to stop making new stars. A galaxy’s central black hole and its slow, long-term ...

A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by ...

Image: Snapshots of the time evolution of a collision of two spiral galaxies with black holes at their center from a computer simulation. Color indicates temperature and brightness the gas density.

"To make progress towards a theory of galaxy formation, it is crucial to compare results and codes from different simulations. We have now done this by bringing together competing code groups behind ...

Milky Way disk flip simulations from Durham University's NAM 2026 presentation show the Milky Way's galactic disk flipped more than 90 degrees after a head-on collision with the Gaia-Sausage-Enceladus ...

Add Yahoo as a preferred source to see more of our stories on Google. A new simulation released by NASA's Ames Research Institute reveals a stunning vision of the evolution of a galaxy. Blue influx ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Cosmological hydrodynamics and galaxy formation simulations combine gravitational dynamics with fluid physics to model the growth of structure from the early Universe to the present day. By solving ...

This animation shows the simulated evolution of a galaxy over 200 million years. While the simulations look very similar with and without the machine learning AI model, the AI model performed 4 times ...

Cosmological simulations have become indispensable tools for understanding the assembly of galaxies within the framework of a ΛCDM Universe. By numerically integrating the coupled equations of gravity ...
